A competition that aims to harness the world's most creative engineering minds for building next-generation military drones is heating up with proof-of-flight videos of the contraptions posted online.

There are plenty of quadcopters that will make kids stuck with off-the-shelf RC choppers drool. Top judging in the first round went to a Death Star-like ball on wheels called the GremLion. It's neat trick? A mid-section that pops open to reveal a pair of rotors.

The GremLion was designed by a team at the National University of Singapore and is shown off in the awesomely narrated video above.

However, the video most liked by viewers, as of this writing, demonstrates a tablet-controlled quadcopter called SwiftFlight. The video's production includes Hollywood-esque on-screen pop-up explanations of the action.

Another crowd pleaser is a video describing icarusLabs's entry, a winged aircraft that hovers inside an office before taking to the skies. It buzzes a park with sustained winds of 10 miles per hour, something we know thanks to the detailed reportage.

The next phase of the competition will be live demonstration of the concepts later this month. A fly-off of the 10 top designs will be held this spring. The winner will receive a $100,000 prize, a subcontract with a manufacturer to develop the concept, and an opportunity to demonstrate it to the military.

Information on the mechanics of a painted lady butterfly's flight patterns gleaned from high-speed video may be used to construct better designs for military drones.

High-speed video cameras are allowing university researchers to document how butterflies gracefully flutter through the air. The U.S. military funded findings may lead to more agile insect-sized drones sent to spy on enemies.

A key finding is that butterflies appear to use their bodies and wings to twist and turn in the air in a way similar to how ice skaters use their arms to control the speed of their spins, explains Johns Hopkins University undergraduate Tiras Lin, who is working on the high-speed video research.

"Ice skaters who want to spin faster bring their arms in close to their bodies and extend their arms out when they want to slow down," he explains in the video news release below.

"These positions change the spatial distribution of a skater's mass and modify their moment of inertia; this in turn affects the rotation of the skater's body. An insect may be able to do the same thing."

To capture the images of butterflies in flight, Lin used video cameras that record 3,000 one-megapixel images per second. To put that in perspective, a standard video camera shoots 24, 30 or 60 frames per second. "Butterflies flap their wings about 25 times per second," Lin notes.

Most of his analysis zeroed in on 1/5th of a second of flight, or about 600 frames.

Lin recently presented his findings at a meeting of the American Physical Society's Division of Fluid Dynamics. While they haven't yet been adopted by next-generation drones, he said they ought to be. To see how else drones could get buggier in the future, check out the stories below.
